Pray unceasingly (1Sol.5:17).

"Pray unceasingly," - labour in prayer, "and you will acquire unceasing prayer, which itself will become accomplished in the heart without much exertion. It is evident to everyone that the commandment of the holy Apostle is not fulfilled by the mere performance of the prescribed prayers at certain hours, but it requires always walking before God, dedicating all works to God, the all-seeing and omnipresent, by warming up the mind in the heart with a warm attitude towards heaven. All life, in all its manifestations, must be permeated with prayer."
